Mad Rock Lotus, size US 8/EU 39 in good condition (pre-owned).
This is the women's/low volume version of the Mad Rock Shark. It's a flexible, aggressive bouldering slipper that can also work for sport climbing.
It is in pretty good condition with very little wear on the rubber (Science Friction). Some glue residue and discoloration is natural, as seen in the Backcountry photos. I'm a standard size 37.5/38 in Scarpa Vapors and Instincts (street shoe 7-7.5) and this fits me well lengthwise. (The Mad Rock rep suggested this size and he was correct—don't size up too much if you want a proper, aggressive fit that fills out the toebox and arch.) However, my foot is narrow and this shoe was still too wide even though it's the LV version. It would work well for someone with normal to wide feet and/or higher arches.
